Boot Image Editor is a Windows-based utility that enables network administrators to create
and manipulate TCP/IP, NetWare, and PXE boot images. The boot image files and menu boot
files created with the Boot Image Editor allow network client PCs to boot from servers
instead of local drives or to perform Pre-OS tasks before booting from the client PC’s hard
disk.
Boot Image Editor combines and enhances the IMAGEGEN, IMGGEN, MAPGEN, and Multiple
Image File Editor (MULTI_ED) DOS-based utilities available from Lanworks Technologies Co.
Although we encourage you to use Boot Image Editor, the DOS-based image utilities
(IMAGEGEN, IMGGEN, MAPGEN, and MULTI_ED) are still available on the MBA Utility disk
and on the EtherCD. The instructions for these utilities and for the BWLOADHI and UNRPLFIX
utilities have been removed from this User Guide and placed into the file OLDUTILS.TXT on
the MBA Utility disk and on the EtherCD.
With Boot Image Editor, you can:
Create boot image files (from standard boot diskettes) that contain standard startup
files and reside on a server.
View and modify the contents of boot image files directly, without creating or
accessing boot diskettes.
Create a menu boot file and designate a list of boot options from which end-users can
choose at boot time.
Create special Pre-OS boot image files that can execute third-party desktop
management agents on the client PC before it boots from the local drive.
Configure boot image file options, such as whether they are read-only or writeable or
have extended or normal capacity.
Convert boot image files between environments, such as TCP/IP images to NetWare
images and vice versa.
Like Novell’s legacy DOSGEN utility, the Boot Image Editor takes a snapshot of a boot
diskette. Without Boot Image Editor, creating, examining, and modifying boot image files is a
tedious exercise. Although the Boot Image Editor can be installed on any computer, it is
usually implemented on a server or a network administration PC. For installation instructions,
see “
Boot Image Editor Installation ” in Chapter 2 “Installing MBA.”
